Abstract
Geosynthetics provide a means to mechanically stabilize earth structures by improving strength through tensile reinforcement. When incorporating these polymeric materials in the application of stabilizing steep slopes, geosynthetic reinforcement can accommodate budgetary restrictions and alleviate space constraints. TxDOT currently has limited use of geosynthetics in steep slope construction. Therefore, a synthesis study of geosynthetic reinforced steep slopes has been conducted to enhance the present understanding of this technology. The study summarized the benefits and limitations of utilizing geosynthetic reinforcement and investigated current design and construction methods in order to determine best practices. Additionally, the cost effectiveness of geosynthetic reinforced steep slopes was examined. Case studies were also identified and assessed to determine optimal soil conditions, geometry of the slope, design criteria, construction specifications, and performance measures. The synthesis study summarized best practices, existing methodologies, and recommendations for the use of geosynthetic reinforced steep slopes in Texas.
